Solving this sort of thing is not about throwing more people at it. That would be brute force and not strategic. Instead, you want to architect systems like these in a way that strikes a good balance between resilience and things like cost/efficiency/etc.

Sure, but laying off a number of good SREs from the Internet traffic team that is responsible for the Google Load Balancer team can't be helping this situation.

This demonstrates yet again why global configurations, global services, and global anycast VIP routing should be considered an anti pattern. gcp should be designed in a way where the term “global outage” isn’t a word in their vocabulary.

You can't really have 30+ fully independent regions running their own stack with different versions of apps and separate secrets, IP/routing and certificates in each. At some point you have to unify or it becomes either unmanageable or inconsistent.

Right. You want regions to be fully independent, yet the software stacks they are running to be fully synchronized and consistent. So there’s a tension. If there’s a sleeper bug that wakes only after it has been rolled out to every region, you’ve got a global outage. Given the increasing complexity of these systems, it will always be possible to find all those.

This is why any criticism of AWS reliability is meaningless to me. All the cloud providers go down - all of them. Either you are multi-cloud, or you run your own hardware, but these events are inevitable.

Is anyone tracking reliability for these public providers? Would be curious how AWS compares to Azure and GCP. My experience is it's better, but we may have avoided Kinesis or whatever that keeps going down.

Ouch some pain at google today then. I hate to wake up on a Monday morning to this. <3 To the engineers trying to fix it at the moment.

Google has follows-the-sun on-call rotations for large rotations, so this hit the UK team just after lunch.

Ah so the rotation rotates to match the current rotation. Very smart.

The amount of time you are down vs. up dictates your SLOs and SLAs. Criticism of how reliable one vs. another is is not only valid, it's backed by hundreds of millions of contractual dollars and credits every year. We spend tens of millions on AWS per year. We have several SLAs with them. Our Elasticache SLA was breached once (localized to us - not whole customer base) and we got credits which were commensurate with the amount of business we lost during that downtime period.

If one provider is down more than the others, the criticism is not only valid, it results in real business loss for the provider and its customers.

On multi-cloud: it's one way to reduce the amount of downtime you have, but it comes with a significant operational cost depending on how your application is architected and how your teams internal to your company are formed. It is totally practical for someone to bank on AWS' reliability until they're at a significant amount of traction or revenue where the added uptime of going multicloud is worth the investment. I know you're not saying this isn't the case (I think you're saying "do that if you're going to complain about 1 providers' uptime"), but thought it was worth putting the context into the HN ether.

do you mean the cloud provider can't, or the customer can't?

05:41 - 06:26 PT, 45 min total. Not great, not terrible.

Yep. Of course there's no detail yet so we don't know what exactly was affected. All we can see is "Multiple services are being impacted globally" and a list of services (Build, Firestore, Container Registry, BigQuery, Bigtable, Networking, Pub/Sub, Storage, Compute Engine, Identity and Access Management) but there's no indication of what specifically was impacted. Could you still see status for your VMs, but not lau…

It's weird, I did a cursory search and can't find people complaining about that 8 day long networking issue. I wonder if the latency was just barely out of SLO so people didn't notice? Or since it was a telecom problem, maybe it was part of one of the recent undersea cable outages so people weren't surprised enough to remark on it? Or maybe I'm just not searching well.

(full disclosure, work at Google but not on cloud stuff)
